Study Notes
Renal Function and Blood Pressure
- Normal range for Creatinine (CR) is 0.5-1.1 mg/dl
- High level of Blood Urea Nitrogen (BUN) indicates kidney dysfunction or damage
- Hemodialysis uses a dialysate solution to clean the blood
- Diuretic Drugs help to reduce excess fluid and sodium in the body
- Renin regulates blood pressure by constricting blood vessels
- Angiotensin II causes vasoconstriction, increasing blood pressure
Hormonal Regulation
- Angiotensin Converting Enzyme (ACE) Inhibitors help to reduce blood pressure by inhibiting Angiotensin II
- Vasopressin is also known as Antidiuretic Hormone (ADH)
- ADH helps to regulate water reabsorption in the kidneys
Acid-Base Balance
- Metabolic Acidosis occurs when the body produces too much acid or cannot remove enough acid
- Metabolic Alkalosis occurs when the body produces too much base or cannot remove enough acid
Blood Pressure Regulation
- Blood pressure is sensed by baroreceptors in the body
- Mean Arterial Blood Pressure (MABP) is calculated using the equation: MABP = (2/3)DBP + (1/3)SBP
- Normal urine output per hour is 1-2 ml/kg
Kidney Function
- Primary function of the kidneys is to filter waste and excess fluids from the blood
- Nephron is the functional unit of the kidney, consisting of glomerulus, proximal convoluted tubule, loop of Henle, and distal convoluted tubule
- Juxtaglomerular apparatus regulates blood pressure by releasing Renin
Renal Function in Different Conditions
- In Congestive Heart Failure (CHF), the heart is unable to pump enough blood, leading to fluid buildup and increased blood pressure
- Average number of nephrons per kidney in an 80-year-old person is approximately 1 million, decreasing from 2 million at birth
- Reduced vascular volume stimulates the renin-angiotensin-aldosterone system (RAAS), leading to increased blood pressure
